Fitbit also announced that its Fitbit Labs Sleep Score beta program will be open for enrollment to qualifying Fitbit users starting in November. Fitbit users who are accepted into the beta will receive a nightly score that provides a more complete picture of their overall sleep and what factors affect it based on key metrics tracked by any Fitbit device with advanced 24/7 PurePulse heart rate tracking. For devices with a relative SpO2 sensor, including Fitbit Charge 3, Fitbit Ionic and Fitbit Versa, Fitbit will also be testing for breathing disruptions. In the future, with FDA approval, the data from this sensor technology could indicate more serious health conditions, like sleep apnea.

Fitbit Charge 3 will be available worldwide beginning October 7. The device will also available for sale at Fitbit.com and major online retailers for $149.95 (USD) in black with a graphite aluminum case or blue gray with a rose gold aluminum case; accessories range from $29.95-$49.95 (USD). Coming soon, Fitbit Charge 3 Special Edition with Fitbit Pay will be available for $169.95 (USD).
